Application filed June 23, 1887. Serial No. 242,254. (No model.)

Be it known that I, ALBERT L. MURPHY, a

I citizen of the United States, residing in the and an outlet or drawingport, 0.

city and county of Philadelphia, State of Pennsylvania, have inventedanew and useful Improvement in Butt-Welded Gas and Steam Pipes, whichimprovement is fully set forth in the following specification andaccompanying drawings.

My invention relates to improvements in the manufacture of butt-weldedwrought-iron pipes, and in a novel and improved .method of drawing bentskelps when heated to welding heat, by attaching to the skelp while atsuch welding heat a tag, also heated at one endto welding heat, thendrawing the skelp, and afterward removing the tag.

. The object of my invention is to providea cheap, simple, and effectivemeans for withdrawing skelps in the process of welding; and to thislcndit consists in a novel method of drawing bent skelps from thewelding-furnace when heated to a welding heat, by attaching to the skelpwhile-thus heated a tag, usually hollow in form and heated at one end toa welding heat, thus uniting the skelp and. tag, and

then drawing the skelp, through the agency of the tag, from the furnace.

I will now describe my method of procedure.

Aftera short time the two unite 5o The bent skelp is placed inthe welding-fur- 15s. at welding heat, when the skelp is drawn incompleted condition. The. exterior end, L, of I the ag, having beenoutside of the furnace, is sufficiently cool to enable it to.be used asa handle for manipulating the skelp. The skelp and tag are then carriedtothe shears and'cut apart. I make the tag hollow for the sake oflightness and economy of material, and utilize for such purpose oldscraps or other cheap parts of iron.

handle bent skelps with tongs and analogous devices. Such apparatus areexpensive, and

owing to theintense heat of the furnace are soon destroyed and needrepairing.

The apparatusl use is cheap, simple, and

Prior to my invention it was customaryto effective, and enables me-topractice my novel;

method in sucha manner as to avoid these ob; jectionable features. I 1

Having thus described my invention,whatI claim as new, and desire tosecure by Letters. Patent, is v 1. The improved method or process ofpre-'' paring skelps for handling in a welding-furnace, consisting ininserting into one end of a are united, and then withdrawing the skelpby means of said tag, substantially as de'-- scribed. v

2. Theimproved method of preparingskelps 'for handling inawelding-furnace, consisting.

in heating the skelp to a welding heat and in-. wserting theretoone endof a handling tag ALBERT L. MURPHY.
